I'm just wondering about something. I'm using a TV for a monitor, and it has a DVI port, a VGA port, and a HDMI port. I'm currently using the HDMI port, and am going to when I install the graphics card I'll use it then too.
However, my question is why? Is it supposedly better? What is the superior connection, with better quality or whatever, or is there any difference except plugs?
I don't know about quality, but having audio in the same cord is pretty nice.
Someone correct me if I'm wrong, but doesn't HDMI have a 40 ms response time?
So it's a little slow compared to dvi/vga.
I've been thinking this myself.
HDMI is more compact, and more simple.
And it does transfer sound signals.
But isn't 1920 x 1080 the maximum res supported?
HDMI is perfect for it, its a HD output, if your computer has one, and so does the tv, it will be fine. but get the normal monitor (DVI) just incase you need to use it for a different monitor.
HDMI and DVI will give the same visual qualily... Better than VGA.
Three things that aren't immediately obvious:
Some TVs/Monitors don't like HDCP over DVI.
Some TVs/Monitors don't have an extra input for audio when using HDMI. (If internal speakers are your thing) - So make sure you can put audio into your HDMI send if it is required.
Some TVs/Monitors don't handle some resolutions over HDMI (This very much the case with older HDMI equipped TVs)
A Word on input Lag on HDMI - If you absolutly must have this faster - disable all image processing on your TV, Sometimes chucking a progressive instead of interlaced signal can help, also send a signal of native resolution.
This article is a good read if it really concerns you: [url]http://blog.arogan.com/2008/09/lcd-hdtv-input-lag-tests.html[/url]
I can confirm that turning off image processing on a TV really helps. I tried playing with a xBox 360 on my HDTV, and there was like, one second of delay; then I remembered that there was a gaming mode. And yeah, it disables all that fancy image smoothing tech.
Other than that, it's pretty much the best standard for now (I think there's another one coming soon, can't remember the name though)
Its basically DVI with sound capabilities. So it is better more or less.

early HDMI, yes, but the current spec, 1.3, and the soon to be spec, 1.4, don't/won't have that problem.
Anyway, there's not really any advantage over DVI aside for the audio, and if you're on a desktop, chances are you don't need the audio portion. They have very similar limitations (ie 1920*1080/1200 at 60/59Hz in 32-bit color). HDMI 1.4, of course, is much better than both, but I really doubt there are any HDMI 1.4 compliant videocards and monitors right now. Could be wrong, though.

HDMI 1.3a-c can do 1920x1200 as well up to 48-bit color, and if in 24-bit or 30-bit color, 2560x1600. HDMI 1.4 can to 4k up to 36-bit color, which is really impressive, but for the most part useless unless you have a literal home theater with a 4k projector and can somehow get your hands on 4k movies.
Fucking hell 4k movies are massive

4K?
What's the exact res of that?
4000 horizontal points. Digital cinema, no consumer display can show it.
So far as I understand from researching hdmi->dvi adapters, the video signal in hdmi is exactly the same as in dvi, so no conversion has to be done and all an adapter has to do is put the right pins in the right sockets. Basically, HDMI = DVI.
But with sound.
I have always assumed that HDMI was for up to 1080p, DVI was for up to 720p and anything below that (EG: 15 pin VGA or component video) was for up to 480p.
HDMI generally has a lot more bandwidth though and is backwards compatible with the DVI protocols albeit at slower speeds.

...you're horribly illinformed
You know DVI carries WQXGA right? The 30" wide resolution.
I like HDMI. With my Xbox, it makes it a lot simpler plugging in one cord that 5.
DVI if you want better response time, HDMI if you want minimalistic setup.
If you want to know (if it'll make any difference) I use DVI for my Desktop PC @ 1080p. And HDMI for an external display for my Laptop.
P.S. HDMI is more universal when it comes to display inputs. As I really yet have to see a TV/Projector with DVI input.
HDMI and DVI are both digital, high-definition capable means of video transfer and from what I can tell, they can be expected to deliver the same quality. And if there is a difference, on a television, it will be negligible.

With two DVI.

This new font is shit, use Segoe UI.
Display port is the king of all current digital video connectors. It can carry resolutions exceeding 2560x1600, and audio, and USB hub/other functionality.
Version 1.2 will allow you to daisy-chain monitors.

However, it came down to a simple decision between DVI and HDMI, I'd pick DVI unless you really need audio over the cable.
If he already has a working HDMI connection it should make 0% difference and just waste time.
I've had my computer connected to my 1080 TV through a VGA, I really can not see the difference in quality from when I play a game through the XBox360 with HDMI.
Is there really that much difference? I don't notice it, and everything is configured correctly both hardware and software wise.
I noticed a vast colour improvement. - Same computer, I just changed from VGA to HDMI.

Yes, display port is the best, yet my screen doesn't support it so I'm stuck with HDMI and VGA.
I think it is.

I could understand colours being more vibrant and things, but for some reason when I compare compare the colour white on both my computer monitor and the TV, the TV gives of a pure white, while my monitor is a mucky grey white. Same with some bright colours too like Yellow.

most TVs within the last 2 years or so have DVI inputs, even more than that use VGA, which is fine for 720p. VGA isn't good for 1080p though just because you're blind doesn't mean it looks good (not to you just anyone who thinks vga isn't bad)

food for thought: maybe you haven't calibrated your monitor at all

display port would be much better if anything worthwhile used it aside for a few monitors here and there

there's a huge difference.
first, VGA is analog, this means right from square one it will not and cannot look as good as a digital input, seeing as it's a digital display. a digital input would be DVI or HDMI for example.
Much like composite, also analog, VGA can indeed carry a signal with that resolution, but that doesn't mean it'll really look good. Composite isn't necessarily limited to 640x480, i've sent through 1280x960 back in the day, but it didn't look any better than 640x480 at all. VGA is somewhat similar, it starts to reach its limits around 1280x1024. After that, colors tart to get muddy, detail gets lost, colors bleed, and depending on the display, a bit of an outline around everything because it tries to sharpen to compensate.
[editline]11:33AM[/editline]
hell, component is better than VGA. component's also analog, and depending on the devices using it, can do 1080p fine (again in analog but still), though most devices will only be able to do 1080i tops. still looks better than VGA, though.
take this with a grain of salt this is all just my own personal first hand experience.
Am I really losing that much using VGA at 1680x1050? I can't really tell.

Same with my PS3. HDMI for the win.
[QUOTE=Odellus;21429930]Am I really losing that much using VGA at 1680x1050? I can't really tell.[/QUOTE]
if your monitor has both a DVI and a VGA port, hook both up, set one of them to be a duplicate of the other in the options (either Control Panel, ATi Catalyst, or nVidia Control Panel). then switch back between the two.
